Microsoft has released an out-of-band update to fix a restart loop issue affecting certain Windows Server devices after the April 2026 update. The problem arose after installing the April 2026 Windows security update (KB5082063), causing domain controllers in multi-domain environments using Privileged Access Management (PAM) to experience LSASS crashes during startup, leading to repeated restarts and potential domain outages. The update targets Windows Server versions 2016 through 2025 and includes hotpatches for failed installations. Only Windows Servers were affected, while some enterprise devices may need to enter their BitLocker recovery key after the first restart post-installation. Microsoft has issued similar updates recently, raising concerns about the frequency of these occurrences.

Some Windows 11 users are facing a restart loop issue after installing the June update KB5039302. This issue mainly affects enterprise machines running virtual machines tools and nested virtualization features, so home users are less likely to be impacted. The update is not mandatory and not a security update, so users should proceed with updating as usual. Windows 10 end-of-life is approaching on October 14, 2025, and users are urged to upgrade to Windows 11 to continue receiving security updates and technical support.
